GUI-Based Dielectric Elliptical Cylinder Parameters Optimization for Front Echo Reduction in Pulse Scattering Analysis

This article proposes a novel numerical approach to reduce scattering echoes in the front area of dielectric objects using a Gaussian radio pulse covering a frequency range of 6-12 GHz. The approach optimizes the dimensions and dielectric permittivity of an elliptical cylinder to ensure the incident pulse create practically no echoes in the front region. A newly developed user-friendly graphical user interface program package facilitates the optimization process, allowing to explore different geometries and permittivity configurations with the slider in its interface and achieve minimal echo in the front region, thus enhancing the invisibility or reduced detectability of dielectric objects in various scenarios.
